Kodi 1oz Copper Ndi Yonenepa Bwanji?

M'makampani osindikizira a board board, njira yodziwika bwino yofotokozera makulidwe amkuwa pa PCB ndi ma ounces (oz). Chifukwa chiyani mugwiritse ntchito yuniti yolemetsa kuti mutchule makulidwe? Funso lalikulu! Ngati 1oz (28.35 magalamu) wamkuwa ataphwanyidwa kuti aphimbe mofanana ndi 1 square foot of surface (0.093 square mita), makulidwe ake adzakhala 1.37mils (0.0348mm). Tchati chosinthika cha miyeso yosiyanasiyana chikhoza kupezeka pansipa.

Ndikufuna Copper yochuluka bwanji?

Pambali yayikulu, ma PCB ambiri amapangidwa ndi mkuwa wa 1oz pagawo lililonse. Ngati mafayilo anu alibe kusindikiza kwa nsalu kapena zina, titha kuganiza kuti 1oz yomaliza kulemera kwa mkuwa pamagulu onse amkuwa. Ngati mapangidwe anu amafunikira ma voltages apamwamba, kukana, kapena zolepheretsa, mkuwa wokulirapo ungakhale wofunikira. Pali zida zingapo zapaintaneti zomwe zingakuthandizeni kudziwa makulidwe, m'lifupi kapena kutalika kwa zomwe mukufuna kuti mukwaniritse zomwe mukufuna. Zida zingapo zotere za chipani chachitatu zalumikizidwa pansipa. PCB Prime sagwirizana ndi olemba zida izi.

 

Kugawa Mkuwa

Monga lamulo, mkuwa uyenera kugawidwa mofanana momwe mungathere pakupanga kwanu. Osati kokha ponena za makulidwe amkuwa pamtundu uliwonse, komanso momwe amagawidwira pagawo lililonse. Inde, izi sizingatheke nthawi zonse, koma kumbukirani izi mukamakonza.

Plating ndi etching ndi njira organic m'lingaliro lakuti copper clad laminate kumizidwa mu nkhokwe ya mankhwala kuti kukonzedwa. Palibe kuwongolera bwino komwe mkuwa umachotsedwa kapena kuyikidwapo. Pa nthawi ya etch, chithunzi chomwe akufuna kuti chitetezedwe ku etchant, koma mankhwala omwe ali mu thanki amasungunula mkuwa pamitengo yosiyana pang'ono kutengera zomwe zili pagawo, kuyika kwa gululo mkati mwa thanki yokha, komanso momwe zimakhalira. kapena mocheperako zida zamkuwa zimagawidwa.

Njira yothetsera mankhwala mu plating ndi etching tanks imagwedezeka ndikuzungulira panthawi yokonza kuti achepetse kusagwirizana kumeneku; komabe, gulu lokhala ndi kachulukidwe kosiyanasiyana kamkuwa litha kukhala lovuta. Pa nthawi ya mapangidwe anu, yesetsani kugawa mkuwa wanu mofanana pa bolodi lonse m'malo mokhala ndi malo akuluakulu otseguka omwe ali ndi zochitika zapadera.

MMENE MUNGASANKHA KUNENERA KOYENERA PCB COPPPER

Kusankha makulidwe oyenera a mkuwa wolemetsa kuti mugwiritse ntchito pokutidwa ndi dzenje (PTH) kumakhala kofunikira kwambiri pakudalirika kwa bolodi losindikizidwa. Pali zinthu ziwiri zofunika kuziganizira pamene kudziwa mulingo woyenera kwambiri PCB mkuwa makulidwe. Yoyamba ndi mphamvu yamakono ya mbiya yovomerezeka kutentha kutentha. Chachiwiri ndi mphamvu mawotchi anatsimikiza ndi makulidwe mkuwa, dzenje kukula ndi ngati pali thandizo vias kapena ayi.

Makasitomala ambiri amafuna kupanga ma PCB ochita bwino kwambiri pamtengo wandalama. Gawo loyamba ndikusankha makulidwe oyenera amkuwa amtundu wanu wa PCB. Makhalidwe apadera a makulidwe awa ndi ofunikira pakuzindikira ntchito, magwiridwe antchito a PCB. Ngati mungafune kudziwa zambiri za kusankha kwa makulidwe a PCB kapena momwe mungasankhire mawonekedwe abwino a PCB, chonde titumizireni. Sitikupereka upangiri wabwino komanso yankho lathunthu. Mupeza ma PCB ang'onoang'ono komanso anzeru omwe amagwira ntchito bwino komanso odalirika kwambiri kuchokera ku YMS.
